SPECIFICATION forming part of Letters Patent No. 430,361, dated June 17,1890. Application filed March 10,1890. Serial No. 343,377. (No model.)

To all whmn it ntc y concern:

Be it known that I, DANIEL J. ARPIN, of Grand Rapids, in the county oflVood, and in the State of Visconsin, have invented certain new anduseful Improvements in Rut- Cutters; and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention relates to rut-cutters for iceroads; and it consists incertain peculiarities of construction and combination of parts, to behereinafter described with reference to the accompanying drawings andsubsequently claimed.

In the drawings, Figure 1 represents a side elevation of a portion of asled-runner provided with a rut-cutter constructed according to myinvention; Fig. 2, a longitudinal section; Fig. 3, a plan View, partlyin horizontal section; and Fig. 4, a transverse sect-ion with partsbroken away.

Referring by letter to the drawings, A represents a sled-runner cut outto form a recess having an inclined rear face, against which rests thetransverse wall b of a shell B, the latter being of a form correspondingto the contour of the runner, to which it is fastened by screws or othersuitable means, and in this connection attention is called to the factthat my device may be used with either a round or flat runner, the shellbeing curved or angular in general contour, according to the shape ofthe runner it is to fit.

As shown, the main portion of the shell is set in flush with the runnerand has a wing c on the outside at right angles to said runner. Hingedto the wing c is a plate d, preferably turned up at its outer forwardcorner, and joined to said wing and rear portion of the shell is afendere, the latterbeing oblique to the sled-runner. A bolt f is passedthrough the transverse wall I) of the shell to engage a longitudinalslot gin a knife 0, the latter being adjustably held in place by aset-nut h on the bolt f, as best illustrated in Fig. 2. The cutting endof the knife 0 extends through an opening 2' in the bottom of the shellB, and is preferably concave. While I have shown the knife as having itsout straight across the line of draft, it is obvious that the device maybe so constructed as to vary the angle of said knife, whereby the lattermay have more or less of a shear out.

In the operation of my device the knife is adjusted to suit the depth ofcut desired, and the chips and dirt coming from said knife are preventedfrom falling back into the rut by means of the wing c on the shell B andhinged plate (1, the latter being free to work up and down, according tothe roughness of the surface over which it travels. This vibratorymovement of the hinged plate causes the chips, &c., to shake off farenough away from the sled-runner to prevent their falling back into therut before the fender c has an opportunity to throw them still fartherout as said runner travels forward.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A rut-cutter for attachment to a sled runner, the same comprising ashell having a general contour corresponding to that of said runner, atransverse wall, and a rightangled wing, and a knife connected to saidtransverse Wall to extend through the bottom of the shell, substantiallyas set forth.

2. A rut-cutter for attachment to a sledrunner, the same comprising ashell having a general contour corresponding to that of said runner, atransverse wall, a right-angled wing, and a plate hinged to the wing,and a knife connected to said transverse wall to extend through thebottom of the shell, substantially as set forth.

3. A rut-cutter for attachment to a sledrunner, the same comprising ashell having a general contour corresponding to that of said runneig'astationary transverse wall, and

an oblique fender, and a knife connected to said transverse wall toextend through the bottom of the shell, substantially as set forth.

4. A rut-cutter for attachment to a sledrunner, the same comprising ashell having a general contour corresponding to that of said runner, atransverse wall, a right-angled wing, a plate hinged to the wing, and anoblique fender, and a knife connected to said transverse wall to extendthrough the bottom of the shell, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atGrand Rapids, in the county of Wood and'State of \Visconsin, in thepresence of two witnesses.

DANIEL J. ARPIN.
